According to a report published today by Shoebat, a letter dated Aug. 30, 2011, informed the al-Qaida member he had responsibility for security in Tripoli “to include all international embassies.”

The letter was to Abdel Hakim al-Khowailidi Belhaj and signed by Mustafa Muhammad Abdul Jalil on behalf of the National Transitional Council, with which the U.S. was working after Moammar Gadhafi fell from power in Libya.

Belhaj previously has been described by al-Qaida kingpin Ayman al-Zawahiri as “the amir of the mujahideen, the patient and steadfast [Belhaj].”

Shoebat, who was joined by talk-show host Ben Barrack in the investigation of the document, said the letter was from “a treasure trove of secret documents” obtained by a Libyan source.

“It shows that in supporting the removal of Gadhafi, the Obama administration seemed to sign on to an arrangement that left forces loyal to al-Qaida in charge of security at the U.S. embassy in Tripoli from 2011 through at least the spring of 2012,” they wrote.

The letter, translated by Shoebat, said: “We would like to inform you that you have been commissioned to the duties and responsibilities of the military committee of the city of Tripoli. These include taking all necessary procedures to secure the safety of the Capital and its citizens, its public and private property, and institutions, to include all international embassies. To coordinate with the local community of the city of Tripoli and the security assembly and defense on a national level.”

Shoebat explained that al-Zawahiri’s endorsement of Belhaj came in a 2007 interview that was replayed by ABC.

The report also said Belhaj had been identified as “a Libyan rebel and a moderate person who commands wide respect,” but Shoebat noted the source of that statement was “a leader with the Libyan Muslim Brotherhood” – Al-Amin Belhaj.

Also, Ali Sulaiman Aujali appeared at a convention for the Islamic Society of North America, widely considered a front group for the Muslim Brotherhood in America, and then vouched for Belhaj, Shoebat reported.

The Libyan ambassador to the U.S. said at one point that Belhaj “should be accept[ed] for the person that he is today and we should deal with him on that basis.”

The Benghazi controversy has been developing since Sept. 11 when on the anniversary of the 9/11 attacks Ambassador Chris Stevens and three other Americans were killed in an organized terror attack.

While evidence now indicates the White House knew almost immediately it was an organized, planned terrorist attack, for weeks officials blamed the deaths on Muslim anger over a trailer of an online movie critical of Muhammad.

Reports now have emerged that there were orders for the U.S. military to stand down and not respond to calls for help from Benghazi.

According to Shoebat’s report, the documents from Libya suggest secularists there increasingly want to see Mitt Romney defeat Obama.

Shoebat is the grandson of the Muslim mukhtar, or village head, of Beit Sahour-Bethlehem, who was a friend of the Grand Mufti of Jerusalem, Haj-Ameen al-Husseni, an ally of Adolf Hitler.

After serving as a member of the Palestinian Liberation Organization and participating in acts of terror against Israel, Shoebat studied the Tanach, the Jewish Bible, in a challenge to convert his wife to Islam.

Six month later, he says, he realized that everything he “had been taught about Jews was a lie.”

Convinced he had been on the side of evil, he became an advocate for his former enemy.
